📌 Product Overview
The XL-2214UYC is a compact surface-mount device (SMD) LED designed by XINGLIGHT. 💡 It features a 2.2x1.4x1.35mm outline with a transparent colloid optimized for yellow light emission (585–595nm). Target applications include commercial lighting, automotive interiors, and LCD backlights. The design focus here is balancing a wide 120-degree viewing angle with robust thermal management in a miniature footprint, ensuring reliability in automated SMT production lines.
💡 Typical Applications
Based on its optical characteristics and compact size, the XL-2214UYC is suited for:
- Commercial & Indoor Lighting: Ideal for status indicators and small-scale illumination fixtures.
- Automotive Interiors: Suitable for dashboard lights and soft cabin lighting due to consistent color temperature.
- Signage: Used in advertising light boxes and illuminated channel letters.
- Backlighting: Provides uniform light for LCD switches and display panels.
- Flexible Strips: 📈 Its low profile allows for integration into dense decorative light strips.

- Packaging: EIA standard compliant packaging ensures compatibility with most automated pick-and-place machines.
❓ FAQ
Q: What does the MSL 3 rating mean for my assembly process? A: MSL 3 (Moisture Sensitivity Level 3) means the XL-2214UYC must be mounted within 168 hours (1 week) after opening the vacuum-sealed bag. If exposed longer, you must bake the components at $125^\circ\text{C}$ for 24 hours to prevent popcorning or delamination during reflow.
Q: Can I drive this LED at 30mA for higher brightness? A: No, the datasheet specifies the Absolute Maximum Forward Current as 20mA. While pulsed operation allows up to 80mA, continuous DC operation above 20mA will rapidly degrade the junction and shorten the lifespan of the component.
Q: What is the typical forward voltage I should design for? A: You should design your driver circuit to accommodate a range of 1.9V to 2.3V. Using the typical 2.0V-2.1V is fine for calculations, but ensure your current limiting resistor works safely up to the 2.3V max.
Q: How do I interpret the brightness codes (e.g., E1, E3)? A: These codes (D9 through E4) represent luminous intensity bins. For example, 'E3' guarantees 450-500 mcd, while 'E4' guarantees 500-600 mcd. Selecting a specific bin ensures visual uniformity across your product line.
Q: Is this component compatible with lead-free soldering processes? A: Yes, the XL-2214UYC is suitable for infrared reflow soldering and complies with ROHS environmental protection directives. Ensure your profile matches the thermal limits ($260^\circ\text{C}$ max).
